• Game Technologies: DirectX, XNA, XACT, etc. How to control sprite (jpg) with arrow keys

  Hi, i'm very new to programming, and was reading in the help files about recognizing keyboard buttons being pressed and released, but still cannot figure out how to make my simple jpg sprite to move when i press an arrow.  I used tutorial to make the simple game sprite move around the screen and when it hits the edge it bounces, so what i want to do now is remove the sprite movement, keep the bounce, and allow the user to press an arrow key to make it start moving.  As I said, I am very new to programming, although I can understand some technical terms.  Thanks.  Here is the code i'm using. namespace WindowsGame1 { /// <summary> /// This is the main type for your game /// </summary> ...Show All

• Windows Forms DoEvents in a Class Library

  Hi, I have a VC# dll which has a while(true) loop. I was using a DoEvents in the original code, but now when I write the dll I cant use the DoEvents !! Is there a way to use DoEvents in a Class Library Thanks. Yes i know that its not good programming practice. I have a while loop which is waiting for data received (or sent) over sockets. Since I have to keep on listening for data being received, I cant think of a better way of doing this thing without using the while(true) loop. The loop terminates when the client sends an exit message. So, I am using the DoEvents before I enter this loop to allow my program to do other stuff. And yes I know that DoEvents is in Windows.Forms, but that is wher ...Show All

• Visual C++ using some old MFC code in a managed dll

  Hi - I have some low-level C++ code to interface with a chip. The code works fine to open and download a configuration file. However, I want have that functionality from a VB app, so I'm trying to create a managed C++ dll that I can reference, pass the file path from VB and let the old C++ code process and download the file. The C++ code uses afxwin.h with all the old MFC classes, e.g. CString DownloadDlg::GetFileContents(CString fileName) { CFile file(fileName, CFile::modeRead); CString contents; // Create the buffer DWORD fileLength = (DWORD) file.SeekToEnd(); char * pFileContents = new char [fileLength + 1]; file.SeekToBegin(); // Read it in file.Read(pFileContents, fileLength); pFileContents ...Show All

• Windows Forms Data Not Saving In Calculated Field

  I have a textbox that is populated from a calculated variable. The textbox populates ok but when I save the data, the textbox resets to zero and saves to the database as zero. All of the other data on the form saves appropriately.

• .NET Development Can't authenticate against non-Microsoft LDAP server.

  Hello VB.NET gurus! I'm having a miserable time authenticating against a Novell LDAP server at a university. The code (below) that I use works GREAT against my SBS 2003 server. Does anyone have a clue as to as to what I'm missing Thank you for your time!!! My contact at the university pulled up some log of this query and stated that I keep doing a 'non-authenticated bind' with this code. This works: Dim path As String = "LDAP://x.x.x.x/DC=a,DC=local" Dim username As String = "CN=PersonName,OU=SBSUsers,OU=Users,OU=Gap,DC=a,DC=local" ' This doesn't work: 'Dim path As String = LDAP://x.x.x.x/o=wcslc ' Dim username As String = "cn=PersonName,ou=campus,o=wcslc" ...Show All

• .NET Development Original table of view column

  I need to know the underlying table of a column in a view. Using getschema("Columns") i can get a list of the columns in the view, but not the table that they come from. Using getschema("ViewColumns") gives me the table that they come from but not if they are visible or not in the view... it includes all columns from all tables in the view regardless if they are visible in the view or not. What I need is to get a list of columns in the view and the table that they belong to. What's the best way to do this Any advice Hi siftee, I think you have to use the the information_schema views from SQLServer - if you are using it - Here is a link where you can find how to use them Bes ...Show All

• Visual FoxPro How to disable Foxpro screen?

  I have a project with one screen form only. When I run the execute, the screen form is within the foxpro's screen. How do I make the screen form as the only window form shown on screen Thanks. Joe. screen = off in config.fpw is the best solution. Toplevel forms can NOT be modal (even if you set to modal it is ignored). You need "read events" to start the event processing and to prevent the application's immediately ending (flashing and closing). Here is a simple one form layout: * Form.init (showwindow property is 2-toplevel) this.Show read events * A button in form click - "Close Application" button * Button's click code clear events thisform.release * Config.fpw scr ...Show All

• .NET Development Configuration Enterprise Library - OnDeserializeUnrecognisedAttribute

  HI, I'm currently attempting to convert my applications existing configuration to the enterprise library method, and am having some problems. I need to configure groups of items where the items share some generic configuration detail, but must also be able to contain item-specific configuration. I intended to configure this by having the shared configuration as attributes on the item configuration node, and then permit a child node that could contain any specific configuration. I thought that I would be able to parse the child node into an XmlNode property by overriding the OnDeserializeUnrecognisedElement method in ConfigurationElement, but this seems to be causing some problems. If I use the XmlReader.ReadOuterXml() to acquire ...Show All
